The

so re.

diil'crcnce in the depth of the deeper and shallower dei nessions is preferalily equal to the thickness ot the metal hloclzs t on which are fashioned. preferably by treatment in dies. the letters. name-ale or other indicia some with adhesive material. preterahly in the form of a sheet or strip oil? celluloid indicated at (3. This strip I first saturate or in son'ie cases immerse in acetone to cause the celluloid to reach a dissoluhle state, so that when subjected to pressure and heat it will entirely dissolve and leave a gummy or sticky mass to constitute an adhesive to hold the indicia hloehs where adjusted in the deeper (.leprcssion.

I then overlay both the indicia blocks and their indicia as also the shallower depressions 3 with a like adhes've, or strip of celluloid (3 treated as ahovestated.

I then take a piece of wood veneer. of size about the same or a little. larger than the metal base 1, and saturate it with, or subject it to a hath of. dissolved celluloid; or insome eases merely saturate it with a coating: of acetone which will later attack the celluloid. whether in the term of: a strip or already dissolved. when the veneer has been trcatcd to the pressure and heating steps. The rcnecr so conditioned is placed upon the adhesive that lnis been laid over the plate and indicia as above stated.

ll then suhjcetlhe whole composite strueture to pressure. preferably bringing; in contact; with the wood veneer a pressure device in the naturc of a platen having a llat pressure face. This pressure so applied acts to torce the veneer down into the shallower de ression. into any uncovered portions of the deeper depression and. into all hi" the rccesscs within and around the letters. numbers or other indicia. A pressure of lit] to tone pounds per squareinch nuiintained tor from two to ten minutes and am'ompenitul by heat ranging: from 200 degrees I to 250 degrees P. will accomplish. this object.

It will he also undo stood that such pres particularly when accon'ipanied hy heat. will act to thoroughly unite the adhesiv'e material with the metal base and the wood veneer. The adhesive. it in the form 01'' a celluloid sheet, more or less in a dissolving; state. or it already in a .tully dissolved state. acts admirably in tannpleting the state (it dismlution of? this adhesive and. in making a firm and permanent adherence between the metal base and the now inlaid veneer.

fitter proceeding thus far there remains the iinal step of dressiinr-oli' as by grindiini', ahradilug'. or in a sense planing, the exposed venccr to rcinorc the shattered portions and to make the veneer llunll with the border ot the base plate and the laces ot the letters, numbers or indicia. which latter are at the smile time polished so as to stand out in contrast with the. wood veneer now inlaid and forming a hacltgn'ound or held.

lhus the method oi producing my sign and the s nn itsclt will he 'lully understood. it has the tltll'tllll'llffOl-l ot chcapncss in production. du ability and exccediiug beauty or attractiveness.

Flo tar l have let it i assumed that the depressions surroundimz; the letters, numbers or other dcsiejn on thebasc plate would be sullieicntly shallow to readily be tilled with the veneer oi wood. llut there may he cases. as shown in Figure l), where it will. be desirable to cnniloy tillers indicated at 7. These tillers are in the nature of strips, say of metal. adapted to he laid in the deeper recesses to partially till them so that the remainder of their depth can, the more. readily be tilled and oecupied l'iy the veneer of wood. I will usually employan adhesive, such as above set 'l'orth. between the bases ol the recesses and the tiller strips 7 and lietwecn the latter and the vei'ieelu the more pcriectly to retaii'i the veneer in. the depressinus. l i

The individual hlochs it which rarry the letters. numbers or other indicin may be spaced apart as desired by placing luituveen each two blochs a. spacer or spacing stripfl o'li one width or a spacer oi another width as shown at S in Figure Ill.

it will also he understood that I desire to coinprelieiul within my hrsention such modiiications as may be necessary to adapt it to varying conditions and. uses.

Having: thus fully dcscrihed my invcnlion. what l: claim as new and desire to secure by .l letters Patent, is

1. The herein dcscrihed method oi produring a. sign. consisting" in ialnricating a. base ol metal having: a. depresshm tor the reception of raised indicia; in fabricating: the raised indicia on separate blocks and inserting: each hlock in such depression and relatively to the other blocks; in placing a wood veneer over the platoand the indicia; in previously placing; an atlhes-iive to lie between Ithe depression and the blocks and hetween the veneer and tlieplatc and hloclzs; in subjecting the veneer to high flat pressure to force it into all of the exposed recesses lit) ill)

which it overlies; and in then subjecting the ducing a sign consisting in fabricating a metal base with a deeper and a shallower depression; in. applying an adhesive over such deeper depression; in fabricating readable raised indicia on separate blocks; in placing these blocks in the deeper depressions and in proper relation; in placing an adhesive over the indicia and their blocks and the shallower depressions; in placing a sheet of wood veneer over the indicia, their blocks and the shallower depression and any exposed portions of the deeper depression; in subjecting such veneer to flat pressure suflicient in degree and point of time to sink the veneer into allfof the exposed depres sions; and in dressing-off the wood to re.- move' the shattered portions and smooththe inlaid parts and present the indicia therethrough.

3. The herein described method of, pro ducing a sign consisting in fabricating a metal base with a deeper and a shallower depression; in fabricating raised indicia on individual blocks; in overlaying such deeper depression with a strip of celluloid in a dissoluble state; in placing said blocks in said depression over said celluloid; in placing over the shallower depressions, the blocks and the indicia another sheet of celluloid in a dissoluble state; in saturating a sheet of wood veneer with a dissolving agent, such as acetone; in placing such sheet of veneer over the last-named sheet of celluloid; in subjecting the whole to fiat pressure and heat sufficient-to force the veneer into all of the depressions exposed beneath it and to complete the dissolution of the celluloid; and in dressing-off the shattered portions of the veneer to leave the inlaid portions smooth and to expose the indicia.

4-. The herein described method of producinga sign, consisting in fabricating a base of metal having a depression for the reception of raised indicia; in fabricating the indicia on separate blocks and inserting each block in such depression and relatively to the other blocks; in placing filler strips in the deeper depressions; in placing a wood veneer over the plate and its filler strips and over the indicia; in subjecting the veneer to a high flat pressure to force it into all of the exposed recesses and on the filler strips which it overlies; and in then subjecting the article to a dressing-off step to remove the surplus and shattered portions of the veneer and leave the remainder smooth and flush with the indicia.

5. The herein described article, consisting of a base of metal having a depression therein, a series of blocks independentlypositioned in the depression, said blocks having indicia forming raised elements, an adhesive between the blocks and the depression, a veneer of woodseated in the depressions between and within the indicia. and in the plate with an adhesive between the veneer and such depressions, the face or upper surface of the article being dressed-off to give a finish to the veneer and to the exposed indicia.

6. The herein described sign consisting of a metal base having a deeper and a shal lower dep'ression,-an adhesive applied to the deeper depression; individual blocks fitted and positioned within said deeper depression and oversuch adhesive, said blocks having indicia forming raised elements, another adhesive applied upon the upper surface of the plate and blocks, and a veneer of wood seated in all ofthe depressions exposed to it, the whole being polished off on the face or upper surface.

7. The herein described sign consisting of a metal base having deeper and shallower depressions, filler strips in the deeper depressions; individual blocks fitted and positioned within the deeper depressions, said blocks having indicia forming raised elements and aveneer of wood seated in all of the depressions exposed to it including the depressions having the filler strips therein, the whole being polished off on the face or upper surface.

8. In the herein described sign, a metal base having a depression therein, individual blocks fitted and positioned within said depression and having raised indicia; filler strips also in said depression at places not occupied by the indicia blocks, and a veneer of wood seated in said depression at places between the indicia and in so much of the depth" of the depression as not occupied by the filler strips.

9. In the herein described sign, a metal basehaving a depression in one face thereof, individual blocks fitted in such depression and having raised indicia; individual spacing strips between the indicia blocks to properly position them; filler strips in parts of the depression not occupied by said blocks, and a veneer of wood seated in the depression at places adjacent the indicia and over the spacing strips and over the tiller strips.

In testimony whereof, I aflix my signature.
